Bar operator needs to pay attention to what the amount of problems (2010-02-26

 Stirrups is calculated according to the net inter-operator

beam stirrups bearing does not count

calculated through a long steel (through tendons) at one end of the beam when there is one end of the column is a wall that would need to anchor steel

anchorage length and the width of bearing a relationship, not necessarily of equal length at both ends (see 03G101-1)

stirrups is calculated according to calculation of the net cross -50 * 2

debit column when the middle column is calculated above a

structure of the relationship between various components of the connection, that is, who, when the question who the bearing

is based on the columns, bearing wall, bearing column is the beam, the beam is bearing plate, sub-beam to main beam for the stand.

longitudinal reinforcement anchored into the support; transverse reinforcement (stirrups) not enter the bearing into the bearing is not required force structure requirements. Column, wall inserted into the bearing stirrup reinforcement of stirrups can not afford the role of a stabilizing effect only as long as a large box hoop on the line, the real effect of the above column are required from every one stirrup pull one. Beam longitudinal reinforcement is when entering into the bearing, but even the top beam to the required stirrup into the bearing,UGG boots, because the top of the upper part of the force coupling beam reinforcement in the epidermis, anchoring is not reliable,UGG bailey button, it is bound to rely on the stirrups to live, do not collapse out.

beam stirrup length per span length minus the net cross-100MM, that is, the beam stirrups started from the column layout 50MM side column beam stirrups are not arranged,UGG boots clearance, but the column stirrups must be arranged and encryption; this point in the Chinese seismic design code has been clearly stipulated; Beam Bar Anchorage

problem only exists or not and the beam bearing on the bottom, and the bearing columns or walls, or whether the main beam is independent of the other;

beam reinforcement anchorage length within the bearing problem and the type of beam (frame beam  secondary beam) and the bearing type (side bearings  in the bearing) the;

side bearing beam in the framework of the anchorage length is 0.4 times the LAE (LAE as a bond length) + hook 15D (D is the bar diameter); if the edge itself is not less than the width of bearing steel double the anchorage length of steel beam frame, you can not hook the straight anchor,UGG shoes, straight anchor, but this time must be not less than twice the length of the anchorage length; frame beam bottom reinforcement in the anchorage length of bearing the double LAE , long tendons pass across the face of 1 / 3 of the region connection (cold welding or mechanical connection or connections) to be connected to meet the length specification;

secondary beam on the side bearing is a straight section of the anchorage length of the hook 12D + 15D, the anchorage length in the bearing is 12D; remember, this is the framework for the difference between beam and secondary beam;

studs on the beam frame  structure of lumbar ribs  Anti-Twist connection length of the bars, is generally error-prone to be a problem: in the frame beam waist studs and structural reinforcement of the connection length of the beam always is no matter what 15D, the same way anti-Twist bar reinforcement beams as reinforcement of the connection force compliance with specifications;

the length of the main beam stirrups encryption problem, most people only know that the beam is 1.5 times higher, the consensus is wrong. Reality is that a seismic structure, main beam length of beam stirrups Encryption 2.0 times higher, two hundred thirty-four seismic structure, is 1.5 times the high beam.
